SharedKernel: Autonomy dial enum; IModelClient (ModelRequest/ModelCompletion);
IApiConfigResolver (+ ApiConfigSummary/ResolvedApiConfig) — server-side, decrypted.
Integrations module:
- ApiConfig entity (org-scoped) + IntegrationsDbContext (schema "integrations") +
InitialIntegrations migration; the key is AES-256-GCM encrypted at rest (key derived from
Encryption:MasterKey) and never returned to a client.
- Model adapters: StubModelClient (no-network, provider "stub"/"echo"), an OpenAI-compatible
HTTP adapter, and a ModelClientRouter; ApiConfigResolver decrypts server-side only.
- Endpoints: POST/GET/DELETE /api/integrations/api-configs and POST .../{id}/test. Create/
test/delete require ManageApiKeys (owner); listing requires ConfigureAgents (assign-only,
no key). Dev master key in appsettings; override Encryption__MasterKey in prod.
Verified: build green; ArchitectureTests 8/8 (Integrations references only SharedKernel);
IntegrationTests 26/26 incl. a BYOK flow — key never appears in any response, the connection
test succeeds (stub), and a Member is 403'd from create + list.
